"I feel ready. I mean, it's time - it's been a long time coming [and] I'm just happy to get up there and compete," he said.

"We've been here at the [athletes'] village for almost three weeks and three weeks of just intense focus is actually quite difficult to do so a bit of distraction here and there is OK. As you taper off with your training - you can't train 24 hours a day - you do have a few extra hours.

"All of the other athlete are pretty much finished so they're all out celebrating and partying but we just stay as focused as we can but we're also enjoying the experience as well."

Taufatofua said to be a part of the Olympics was a unique opportunity.

"I had two goals coming here: one was to chase down a gold medal, the second goal was to make sure that Tonga and the Pacific is seen.

"We're not major superpowers but we have a lot to offer to the world and we want our culture out there - so it is for Tonga but it's also for the islands in the Pacific.

"I qualified for Oceania so I'm representing Australia, Tonga, New Zealand, Papua New Guinea, Samoa, Fiji - all of those countries - because there's only one athlete per weight division. To get that out to the world was a big goal of ours and we achieved it," he said.

His coach, Master Paula Sitapa, said Taufatofua's Olympic debut would be the culmination of a long journey.

"It's been 20 years of a vision and dream and work and a struggle on the way but it hasn't been changed. Our plan and goal is still the same - we are looking forward to get a medal from this Olympic Games here in Rio and no doubt our plan and purpose for these Games is still the same," he said.

"To get to this moment is quite amazing. It's an amazing feeling to take part in these Olympic Games... We never give up, we never quit and we're looking forward to this Saturday [Rio time]."

Mr Taufatofua's opening round opponent in the men's over 80kg division is Iran's Sajjad Mardani, in the early hours of Sunday morning.
